The invention relates to a process for the preparation of double-side catalyst-coated membranes for electrochemical devices comprising the steps A) producing a first semifinished product - Applying a first ionomer on a first carrier Applying an anode catalyst layer to the first ionomer layer using a first catalyst ink, Drying the anode catalyst layer, B) producing a second semifinished product Applying a second ionomer layer to a second carrier, Applying a cathode catalyst layer to the second ionomer layer using a second catalyst ink, Drying the cathode catalyst layer, C) removing the first and second carriers from the first and second ionomer layers, respectively, and bonding the first semifinished product to the second semifinished product by bonding the first ionomer layer to the second ionomer layer. |
